You could read a book in the time it takes for Rome 2 to calculate AI movements between turns. Our Chris Thursten has made good progress with Game of Thrones. I, meanwhile, tend to make a cup of tea every end-turn event, and then run my empire with the urgency and recklessness of a hyper-stimulated general with a permanently full bladder. To the delight of my internal organs, CA are trying to trim those long AI thinking times down. They've posted a list of fixes made by a beta version of the second patch, which went into testing on Friday, of which "campaign performance optimisations" and "AI round time improvements" are the most welcome. There are also GPU optimisation tweaks listed alongside significant in-game changes to unit speed and morale-battering flank charges. The fix-list is here for your perusal.
